    2014 Prius. I get continuous hi pitched tone from sound system speakers, after driving about 5 miles. Usually on hot days. Happens sometimes on cool days. Doesn't always happen. Will shut off when driving sometimes for over a half hour. Resting in shade makes it go away. Sound comes through the speakers even when the audio is turned off. No error codes. Mechanic is stumped. Any experience this too? Help please

    Then maybe some door don't close completely? While drive and/or reverse if you open the door the buzzer starts making the sound you refer... So maybe it is one of the 4 doors or the rear hatch slightly open (anyway not locked in position) and while driving with the slightest movement it activates the buzzer...

    I resolved the issue. I swapped out the radio with a used on I bought on eBay for $150. Problem solved. Easy job.
